Rebar Straightening and Cutting Machine
CNC rebar straightening and cutting machine for 4-14mm round/deformed steel bars. ±1cm cutting tolerance, 40-100 m/min speed.
A CNC rebar straightening and cutting machine is essential equipment for any steel processing workshop, construction site, or rebar fabrication facility. This fully automatic machine transforms coiled steel bars into precisely cut, straightened rebar segments ready for concrete reinforcement.
Our CNC rebar straightening and cutting machines handle 4mm to 14mm diameter round bars and deformed steel bars, with cutting tolerances of ±1 cm and speeds ranging from 40 to 100 meters per minute, depending on the model configuration. With motor power options from 7.5 kW to 20.5 kW, these machines are designed to meet the demands of small workshops to large-scale industrial steel processing operations.
Our CNC rebar straightening and cutting machines serve a wide range of industries and applications:
The automatic rebar straightening and cutting machine operates through a continuous, automated process:
Coiled steel bars are loaded onto the decoiler or material rack. The 8-meter rack option allows for bulk material loading, reducing downtime between coils.
The steel bar passes through a series of straightening rollers that apply controlled pressure to remove curvature and deformations from the coiled material. The Cr-Mo-V alloy metering wheel ensures precise length measurement during this process.
The traction system (single or dual-traction depending on model) pulls the straightened bar through the machine at a consistent speed. Variable-frequency models adjust traction force automatically based on material diameter.
When the preset length is reached, the CNC control system activates the cutting mechanism. The premium solenoid valve system ensures fast, clean cuts with minimal burr formation. The cut piece is then discharged to a collection area.
The machine continues this cycle automatically, allowing operators to set batch quantities and length parameters via the CNC control console. Production can run continuously with minimal supervision.
The integrated CNC control panel provides one-touch operation for simple, convenient, and effortless machine control. Operators can easily set cutting lengths, adjust speed parameters, and monitor production status through the user-friendly digital interface. This automatic rebar straightener cutter eliminates complex manual adjustments, reducing operator training time and minimizing human error.
Equipped with an aluminum valve body, copper coil, and imported seals, the solenoid valve system ensures responsive hydraulic control. This high-quality component effectively eliminates external oil leakage and makes internal leakage easy to manage, ensuring reliable long-term operation of your rebar straightening machine.
The metering wheel is manufactured from chromium-molybdenum-vanadium (Cr-Mo-V) alloy, providing exceptional durability and wear resistance. This premium material ensures precise length measurement and accurate cutting, maintaining consistent quality even under heavy-duty continuous operation. The robust construction extends service life and reduces maintenance requirements for your steel bar straightening machine.
Advanced models feature variable-frequency dual-traction systems that optimize power delivery based on material diameter and processing speed. This technology provides:
High-capacity models with 8-meter material racks and dual-traction systems ensure stable, continuous feeding of coiled rebar. This design prevents material slippage and maintains consistent tension throughout the straightening process, resulting in superior end-product quality for your rebar processing operations.

VFD models adjust motor speed and torque based on material load, providing:
A rebar straightening and cutting machine combines both functions in one unit—it straightens coiled steel bars and cuts them to specified lengths. A standalone rebar cutting machine (like the GQ series) only cuts pre-straightened bars and cannot handle coiled material. For processing coiled rebar, the straightening and cutting combination machine is essential.
Our machines process steel bars from 4 mm to 14 mm in diameter, covering both round bars and deformed steel bars. Different models are optimized for specific diameter ranges—4-12# models handle up to 12 mm, while 4-14# and 5-14# models extend to 14 mm.
All models provide a cutting tolerance of ±1 cm, ensuring consistent bar lengths suitable for construction reinforcement applications. The Cr-Mo-V alloy metering wheel ensures precise measurement during high-speed operation.
Speed varies by model: standard models operate at 40-55 m/min, while variable-frequency dual-traction models achieve 85-100 m/min. The 5-14# VFD dual-traction high-speed model delivers the maximum 100 m/min output.
An 8-meter material rack is recommended for high-volume operations or when processing heavy coils. It allows continuous feeding without frequent reloading. For smaller workshops or lower volumes, models without racks are more compact and cost-effective.
Yes, our CNC rebar straightening machines are designed to handle both smooth round bars and ribbed deformed bars within the specified diameter range. The straightening roller configuration accommodates both bar types.
